How can I show Login screen forcefully?

I am new on AppAuth. I tried to logout but didn't find specific way to logout.
When I tried to clear my userDefault data but can't come login screen, it take previous from cookies. I tried to add prompt but couldn't able to achieve.

Here is my login code
`

    let request = OIDAuthorizationRequest(configuration: config,
                                          clientId: clientId,
                                          clientSecret: clientSecret,
                                          scopes: [OIDScopeOpenID, "offline"],
                                          redirectURL: redirectURL,
                                          responseType: OIDResponseTypeCode,
                                          additionalParameters: ["prompt": "login"])
    currentAuthFlow = OIDAuthState.authState(
        byPresenting: request,
        presenting: vc,
        callback: { (authState, error) in
            
            if let authState = authState {
                print(authState)
                onSuccess(authState)
            } else if let error = error {
                print(error)
                onError(error)
            }
        })

`
Can anybody help me to resolve this issue please?

No repository file or test is named. Start with the OIDAuthorizationRequest call shown and review AppAuth-iOS authentication and session APIs alongside the provider's cookie behavior. Done means identifying whether AppAuth can force reauthentication and documenting the supported logout or session-reset path.
